Editing Image (section)

=== Two-dimensional images ===
The broader sense of the word 'image' also encompasses any two-dimensional figure, such as a [[map]], [[Graph (data structure)|graph]], [[pie chart]], [[Painting (object)|painting]], or [[banner]].{{Clarify|date=November 2023|reason=This is contradictory to the previous assertion that images can represent non-real concepts, which includes all of the forms described in this sentence.}} In this wider sense, images can also be rendered manually, such as by [[drawing]], the art of painting, or the [[graphic arts]] (such as [[lithography]] or [[etching]]). Additionally, images can be rendered automatically through [[printing]], [[Computer graphics workstation|computer graphics]] technology, or a combination of both methods.

A two-dimensional image does not need to use the entire visual system to be a visual representation. An example of this is a [[grayscale]] ("black and white") image, which uses the visual system's sensitivity to brightness across all wavelengths without taking into account different colors. A black-and-white visual representation of something is still an image, even though it does not fully use the visual system's capabilities.

On the other hand, some processes can be used to create visual representations of objects that are otherwise inaccessible to the human visual system. These include [[microscopy]] for the magnification of minute objects, [[telescope]]s that can observe objects at great distances, [[X-ray]]s that can visually represent the interior structures of the human body (among other objects), [[Magnetic resonance imaging|magnetic resonance imaging (MRI)]], [[Positron emission tomography|positron emission tomography (PET scans)]], and others. Such processes often rely on detecting [[electromagnetic radiation]] that occurs beyond the [[Electromagnetic spectrum|light spectrum]] visible to the human eye and converting such signals into recognizable images.
